>Wolf children.
The dad dies and for the rest of the movie you see how difficult being a single mother is. She moves the furry kids to a farmvill. The girl dog grows up and wants to be a slut. The boy dog grows up and gets molested by a fox.

They both leave their mom before the age of 13 and she spends the rest of her life alone in a house in the middle of no place. realizing that's what motherhood is all about. Pouring your life away into the hearts and minds of your kids only for them to leave you.
